ANSWER
[tex]C_{22}H_{27}F_3O_4S[/tex]EXPLANATION:
Given below is the molecular formula of Fluticasone
[tex]C_{22}H_{27}F_3O_4S[/tex]To determine the empirical formula from a given molecular formula, we will need to take the subscripts of the molecular formula and reduce it to the simplest ratio.
Looking at the molecular formula of Fluticasone, you can see that sulfur has the least subscript which is 1.
Therefore, to reduce the subscripts to the simplest ratio, we will be dividing through by 1
[tex]\begin{gathered} C_{\frac{22}{1}}H_{\frac{27}{1}}F_{\frac{3}{1}}O_{\frac{4}{1}}S_{\frac{1}{1}} \\ C_{22}H_{27}F_3O_4S \end{gathered}[/tex]Therefore, the empirical formula of Fluticasone is the same as its molecular formula
